Emmy Noether
Noether didn’t just find links between symmetry and conservation—she rebuilt mathematics so those links were inevitable.

Noether's theorem
Emmy Noether
Noether's theorem is the rigorous, general proof that continuous symmetries of the action imply conservation laws. It was published in 1918 in Invariante Variationsprobleme. It applies only to smooth, differentiable symmetries in conservative systems. It resolved energy conservation in general relativity. It reshaped theoretical physics’ emphasis toward symmetry.
